Abstract (en)

[origin: EP2124104A1] An apparatus, a method, and a plate made by the method, e.g., using the apparatus. The apparatus includes a light tunnel of light reflective walls with polygonal cross-section like a kaleidoscope, and a light source, located at one end to produce light radiation to the inside of the light tunnel towards the other end. Light entering the light tunnel towards an inner reflective surface of a wall is reflected off the inner reflective surface so that it can emerge from the other end to cure a plate having photo-curable material thereon.
